To all whom it may concern:

Be it known that I, CARL EDWARD a citizen of; the UnitedStates, residing at Hammond, in the co'u-nty of Lakeand State of Indiana, have invented certain new and useful Improvements in Brake-Beam-Balancing Mechanisms, of which the following is a specification;

This invention relates to brakebeam ancing mechanism." i v The object of the invention is to simplify and improve balancing mechanism for brake beams to'provide an arrangement in which the various parts cooperate toproduce good *ig. 2 is a fragmentary enlarged view showing my improved leveling'arrangement with its associated parts;

Fig. 3 is a sectional view taken in the plane of line 33 of Fig. 2; and, I

Fig. 4 is a plan view of the-leveling member. Y The variousnovel featuresof my invention will be apparent from the following descrip-' tion and drawings and will be particularly pointed out in the appended claims.

This invention is disclosed in connection with a railway car truck, including as ring plank '10, to the opposite sides of whic are bal- I connected hangers 11 for supporting a horigzontally arranged rigid-safety bar 12, theends of which underlie associated brake beams 13 for preventing the latter from-falling to the tracks in the event that they be come disconnected from their normal fas-r tenings. I

The safety bar '12 preferably passes through openings 14: in the hangers, and the safety bar is locked with respectto said hangers by spring clips 15, whichare secured to the sides of the safety bar and the ends of which abut the hangers 11. 1

This leveling member is provided with laterally brace opposite sides of the safety hart-o anddoWnWardly turned cars 19 which em-Y prevent lateral displacement of the leveling 1 device.

The leveling member is prevented from loni itudinal movement by the cooperation of ts upturned end' 20 and shoulders 21 formed by a reduced portion 22 which occupies the upper portion of the aperture 14:. This lev cling-device, which rests upon the safety'bar, curves upwardly and finally terminates in the supporting portion 18 uponwhich thef tensionjmember 17' of the brake beam rides.
